HYDROCARBON-OlL-GAS STOVE.

SPECIFICATION forming part of Letters Patent No. 603,010, dated April 26, 1898.

Application filed June 1% 1896. Serial No. 595,347. (No model.)

To all whom it may concern.-

Be itknown that I, HOSEA WV. L1BBEY,a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and usef ul Improvements in Hydrocarbon Oil- Gas Stoves, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to produce a self-contained hydrocarbon-oil-gas stove.

The invention consists of a hydrocarbon-oil reservoir provided with round wick-tubes arranged in series and provided with means for introducing oil and air to the interior of the series, as will be more particularly hereinafter set forth, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a vertical section through a hydrocarbon oilgas stove having three burners and embodying my invention. Fig. 2 is a plan or top View of same. Fig. 3 is a vertical section of a hydrocarbon -oil-gas stove with a single burner. Fig. 4 is a plan or top view of same. Fig. 5 is a bottom view, and Fig. 6 is an enlarged broken detail view to more clearly illustrate the construction of the tubes and the mode of securing them to the bottom.

A represents the hydrocarbon-oil reservoir; 13 13, round tubes that extend from the bottom of the reservoir to a suitable height above the top of same, in between which tubes are placed round wicks C, that are each raised or lowered by a ratchet-wheel D on a rod or shaft E, having a disk F at its outer end, or by any other suitable means. The outer tube B is perforated in order that the oil can freely pass from the tank or reservoir A to the wick O.

G is a tube arranged within the inner tube B, but so as to leave a good air-space between same. The bottom of the reservoir is perforated or provided with a segmental annular opening afor each set of tubes, through which the air may pass to the space between the tubes B and G. The portion of the bottom between the ends of the opening is indicated by a, and is located directly under the short tube G and forms a support for the :portion of the bottom within the opening, which in turn forms a support for the inner tube G,

of which it also forms a bottom. The lower end of the tube G communicates with the reservoir A by a side passage G, so that the oil is free to flow into same without interfering with the central draft of the wick C. In the tube G is placed a wick or packing H, that will absorb the oil and by capillary attraction convey the oil above the wicks G into a vaporizing-chamber I, against the under side of which the flame of the wick O impinges and heats same to a high degree, so that as the oil is carried up by the wick II it is im1nediately converted into gas and passes by the pipes J to the burners K, where it is consumed and may be employed for any heating purposes.

The bottom of the vapor-chamberis inclined from its center or connections with the top of the tube G, so that as soon as the oil reaches the top of the tube it flows down into the depression formed around the edge of the chamber directly over the flame from the circular wick.

The tank or reservoir A is filled with oil through a nozzle L, covered by a screw-cap M, which nozzle is preferably placed in the center of the tank when several burners are employed, as shown in Figs. 1 and 2, or it may be arranged at the side, as shown in Fig. 4.

When in operation, the round wicks G are lighted and the flame impinges against the vaporizing-chamber I, which is thereby heated to a high degree, and the oil that is taken up by the wick H into said vaporizing-chamber I is instantly converted into vapor and passes through the pipes J to the burners K. By this construction a very compact and efficient self-contained hydrocarbon-oilgas stove is produced, which can be employed for heat ing, cooking, or other purpose.

What I claim is 1. A hydrocarbon-oil-gas stove comprising a reservoir, the bottom of which is provided with a segmental annular opening, three tubes secured to the bottom with the ends of the inner tubes lying adjacent to the walls of the 1 Wicks theouter wick being so situated as to heat the chamber, substantially as set forth.

2. A hydrocarbon-oil-gas stove comprising a reservoir, three sets of tubes secured to the bottom thereof and projecting above the top of the reservoir, a passage leading through the outer tubes to the inner tube of each set, a vaporizing-chamber at the top of each set of tubes, a segmental burner for each chamber, said burners lying substantially end to end and forming a circle above the top of the reservoir, said tubes being adapted to. receive
